Designed for high-density alarm and shutdown output signaling, the Bently Nevada 3500/33-01-00 integrated relay module serves as a critical node in machinery protection architectures. This module provides 16 discrete relay outputs that can be programmed using highly configurable voting logic to actuate external annunciators, sirens, or emergency shutdown systems based on alarm statuses from other modules in the 3500 rack. By processing inputs directly over the high-speed internal backplane, it ensures rapid response times crucial for rotating machinery asset protection.

The 3500/33 module is designed to fit standard Bently Nevada 3500 full-size frames. Unlike the 3500/32 4-channel relay module which requires a specific dual-slot assignment in some older rack revisions, the 3500/33 16-channel module optimizes space by delivering dense control capacity in a single card slot. Always verify that your 3500 Rack Configuration Software is updated to version 3.0 or higher to support the 16-channel voting maps natively.
A common issue encountered during commissioning involves using the internal relays to directly switch inductive heavy loads such as solenoids or large contactors. While rated for 2 A resistive switching, switching inductive loads without external suppression (e.g., flyback diodes or RC snubbers) can lead to premature contact welding or excessive EMI noise, which can disrupt adjacent measurement modules in the 3500 rack. We recommend interposing external relays for high-current or highly inductive loads.
When configuring the voting logic, make sure that the "normally energized" or "normally de-energized" state of each relay matches your fail-safe requirements. Relay contacts default to their de-energized state upon a total loss of power to the 3500 rack. Secure the field terminal block utilizing the integrated retention screws to avoid contact resistance issues under vibration.
Before executing module installation or wiring terminal block connections, ensure all external power circuits connected to the relay terminal block are completely isolated and locked out. Relay contacts may be connected to high-voltage grid systems or machine trip lines that can present electrocution hazards even if the 3500 monitor rack itself is powered down.
Identify an open slot in the 3500 monitor rack (excluding slot 1, reserved strictly for the Rack Interface Module, and the power supply slots).
Slide the main 16-channel relay processor module into the front of the rack along the card guides until the connector is firmly seated in the backplane.
Install the matching 16-channel relay standard I/O module into the corresponding slot at the rear of the rack.
Secure the front and rear module retaining screws to establish solid chassis grounding, then re-energize the rack and upload your configuration parameters.
